Description

Technical Field

[0001] The present invention belongs to the technical field of bag dust collectors, and in particular relates to a method and equipment for adaptive fuzzy control of pulse jet dust cleaning of bag dust collectors. Background Art

[0002] Due to the special usage of bag dust collector, it will face a variety of usage situations when it is used, but not limited to the one proposed below. More specifically, especially after long-term use, dust will adhere to its surface, forming a dust layer, so pulse jet cleaning equipment will be used to clean it. Although the pulse jet cleaning equipment can remove the dust attached to the surface of the bag dust collector, there is still lighter dust floating inside the bag dust collector. Therefore, under the flow of airflow, this part of the dust will be driven to attach to the filter bag of the bag dust collector again, thereby reducing the cleaning effect and quality of the bag dust collector.

[0003] Combining the above-mentioned problems, we can find that it is difficult to avoid the above-mentioned problems when using the existing devices on the market. Even if the problems can be solved, they need to be connected to external devices, which makes it impossible to achieve the desired effect. Therefore, we propose a pulse jet adaptive fuzzy control method and equipment for bag dust collectors that can perform multiple dust removals during use. Summary of the Invention

[0004] The purpose of the present invention is to target an existing bag-type dust collector pulse jet cleaning device, which has the advantage of arranging an adsorption component, a lifting component and a vibration component. After the pulse cleaning component removes the dust from the surface of the filter bag structure, the lifting component can drive the adsorption component to move from top to bottom, and utilize the principle of electrostatic dust removal to perform secondary adsorption treatment on the dust floating on the shell structure. When the adsorption component moves to the bottom of the shell structure, the dust attached to the adsorption component can be shaken off under the action of the vibration component, thereby avoiding the dust from adhering to the filter bag structure for the second time. By arranging a pulse cleaning component and a bag dust collector cleaning control system, when the bag dust collector cleaning control system detects that the airflow velocity in the shell structure decreases, the pulse cleaning component is controlled to blow out compressed air to clean the filter bag structure, causing the filter bag structure to produce rapid expansion and impact vibration from the bag mouth to the bottom, causing the dust layer to deform and break, detach from the filter bag structure and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a bag dust collector pulse jet cleaning device, comprising a bag dust collector main structure and a bag dust collector cleaning control system, the bag dust collector main structure comprising a shell structure, the top of the interior of the shell structure is bolted with a partition, the interior of the partition is bolted with a plurality of evenly distributed filter bag structures, the top of the rear side of the shell structure is connected to a fan structure, the top of the front side of the shell structure is bolted with a pulse cleaning assembly, the rear side of the pulse cleaning assembly extends to the interior of the shell structure, the pulse cleaning assembly is used in conjunction with the filter bag structure, the top of the shell structure is bolted with a lifting assembly, the bottom of the lifting assembly extends to the interior of the shell structure, the bottom of the lifting assembly is bolted with a vibration assembly, and the bottom of the vibration assembly is bolted with an adsorption assembly;

[0006] The adsorption assembly includes a cathode wire and a dust collecting plate, both of which are bolted to the bottom of the lower connecting plate, and the cathode wire is arranged between the opposite sides of two adjacent dust collecting plates. The number of the dust collecting plates is several, and two are arranged in a group. The filter bag structure is located between the opposite sides of two adjacent dust collecting plates.

[0007] By adopting the above technical solution, by arranging an adsorption component, a lifting component and a vibration component, after the pulse cleaning component removes the dust on the surface of the filter bag structure, the lifting component can be used to drive the adsorption component to move from top to bottom, and the principle of electrostatic dust removal is used to perform secondary adsorption treatment on the dust floating in the shell structure. When the adsorption component moves to the bottom of the shell structure, the dust attached to the adsorption component can be shaken off under the action of the vibration component, thereby avoiding the dust from attaching to the filter bag structure for the second time. By arranging a pulse cleaning component and a bag dust collector cleaning control system, when the bag dust collector cleaning control system detects that the airflow velocity in the shell structure decreases, the pulse cleaning component is controlled to blow out compressed air to clean the filter bag structure, causing the filter bag structure to produce rapid expansion and impact vibration from the bag mouth to the bottom, causing the dust layer to deform and break, detach from the filter bag structure and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure.

[0008] The present invention is further configured as follows: the cathode wire includes two metal rods, the metal rods are bolted to the bottom of the vibration component, a connecting rod is welded between the opposite sides of the two metal rods, and a plurality of discharge pins are welded on the front and rear sides of the metal rods.

[0009] By adopting the above technical solution, the cathode wire is composed of a metal rod, a connecting rod and a discharge needle, which can be easily used in conjunction with the dust collecting plate to form a non-uniform electric field. The principle of electrostatic dust removal is used to perform secondary adsorption treatment on the dust floating in the shell structure.

[0010] The present invention is further configured as follows: the dust collecting plate includes an upper end cover, the upper end cover is bolted to the bottom of the vibration component, the front and rear sides of the bottom of the upper end cover are welded with flat metal plates, the bottom of the upper end cover is bolted with an anode plate, and a plurality of dust collecting holes are opened inside the flat metal plate, and a dust collecting cavity is formed between the flat metal plate and the side opposite to the anode plate.

[0011] The above technical solution is adopted, by setting a dust collecting plate, which is composed of an upper end cover, a flat metal plate, an anode plate and a dust collecting hole, and the anode plate is used in conjunction with the cathode line. Based on the principle of electrostatic dust removal, the dust passes through the dust collecting hole and is adsorbed on the anode plate. Moreover, since a dust collecting cavity is formed between the opposite side of the flat metal plate and the anode plate, it can guide and limit the movement trajectory of the dust when shaking off the dust.

[0012] The present invention is further configured as follows: the lifting assembly includes a protective shell, the protective shell is bolted to the top of the shell structure, the rear side of the inside of the protective shell is rotatably connected to a screw, the rear side of the top of the protective shell is bolted to a lifting motor, the output end of the lifting motor is bolted to the screw, the surface of the screw is threadedly connected to a screw sleeve, the front side of the screw sleeve is bolted to a moving rod, the bottom of the moving rod is welded with a synchronization rod, the bottom of the synchronization rod extends to the interior of the shell structure and is bolted to the vibration assembly.

[0013] By adopting the above technical solution, a lifting assembly is set up, and the screw can be driven to rotate by a lifting motor. Under the cooperation of the threads of the sleeve and the screw, the sleeve drives the moving rod to move, and thus, under the connection of the synchronization rod, the vibration assembly and the adsorption assembly are synchronously driven to move from top to bottom in the shell structure, thereby facilitating the adsorption of floating dust in the shell structure by the adsorption assembly.

[0014] The present invention is further configured as follows: a limiting rod is bolted to the front side of the inside of the protective shell, a movable sleeve is slidably connected to the surface of the limiting rod, the movable sleeve is bolted to the movable rod, and the bottoms of the screw rod and the limiting rod are respectively rotationally connected and bolted to the shell structure.

[0015] By adopting the above technical solution, by arranging the limiting rod and the moving sleeve, the moving sleeve can be synchronously driven to move on the surface of the limiting rod when the moving rod moves, thereby ensuring the stability of the moving rod during movement.

[0016] The present invention is further configured as follows: the vibration component includes an upper connecting plate and a lower connecting plate, the upper connecting plate is bolted to the synchronization rod, the front and rear sides of the bottom of the upper connecting plate are bolted to rubber pads, a spring is provided between the opposite sides of the two rubber pads, the bottom of the lower connecting plate is bolted to the adsorption component, the top of the lower connecting plate is bolted to a dual-axis motor, and the surface of the output end of the dual-axis motor is sleeved with an eccentric block.

[0017] By adopting the above technical solution, a vibration component is set up, and the two eccentric blocks are driven to rotate by a dual-axis motor. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to obtain the exciting force, thereby causing the lower connecting plate to vibrate, so that the dust on the adsorption component can be shaken off, and the setting of rubber pads and springs can prevent the vibration force from being transmitted to the upper structure, thereby ensuring the stability of the upper structure.

[0018] The present invention is further configured as follows: the pulse cleaning component includes a compressed air tank, the compressed air tank is bolted to the top of the front side of the shell structure, the top of the compressed air tank is connected to several electromagnetic pulse valves, the top of the electromagnetic pulse valve is connected to a flow-equalizing blowpipe, the bottom of the flow-equalizing blowpipe is connected to a venturi tube, and the venturi tube is used in conjunction with the filter bag structure.

[0019] By adopting the above technical solution and setting a pulse cleaning component, the bag dust collector cleaning control system can detect the flow rate of the airflow in the shell structure. When the flow rate drops, the electromagnetic pulse valve is controlled to operate, so that compressed air enters the uniform blowing pipe from the compressed air tank, and the compressed air is blown out through the venturi to clean the filter bag structure, causing the filter bag structure to expand and vibrate rapidly from the bag mouth to the bottom, causing the dust layer to deform and break, detach from the filter bag structure and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure.

[0020] The present invention is further configured as follows: a fixed sleeve is sleeved on the rear side of the surface of the uniform flow blowing pipe, a connecting rod is bolted between the opposite sides of two adjacent fixed sleeves, the top of the connecting rod is bolted to a fixed rod, and the top of the fixed rod is bolted to the inner wall of the shell structure.

[0021] By adopting the above technical solution, the rear end of the uniform blowing pipe can be fixed by arranging the fixing sleeve, the connecting rod and the fixing rod, thereby ensuring its stability in use.

[0022] The present invention is further configured as follows: the input end of the bag dust collector cleaning control system is unidirectionally electrically connected to the power supply module, the bag dust collector cleaning control system includes a central control module, the input end of the central control module is respectively unidirectionally electrically connected to the airflow velocity detection module and the position sensing module, the output end of the central control module is unidirectionally electrically connected to the electromagnetic pulse valve, and the output end of the central control module is respectively unidirectionally electrically connected to the lifting assembly and the vibration assembly.

[0023] By adopting the above technical solution and setting up a bag dust collector cleaning control system, the real-time airflow velocity in the shell structure can be detected by the airflow velocity detection module. When the airflow velocity drops to the set value, the pulse cleaning component is controlled by the central control module to perform the cleaning operation of the filter bag structure. At the same time, the adsorption component and the lifting component can also be controlled to perform secondary adsorption and centralized treatment of the floating dust. When the lifting component drops to a certain distance, this position can be sensed by the position sensing module. At this time, the central control module can synchronously control the lifting component to stop moving, and make the vibration component work, and cut off the power to the adsorption component, so as to shake off the dust attached to the dust collecting plate to the bottom of the shell structure for centralized treatment.

[0024] An adaptive fuzzy control method for a bag filter pulse jet dust cleaning device comprises the following steps:

[0025] S1. When the bag filter cleaning control system detects a decrease in airflow velocity within the housing structure, it controls the pulse cleaning component to spray compressed air to clean the filter bag structure;

[0026] S2. Simultaneously, the bag filter cleaning control system controls the lifting assembly, causing the adsorption assembly to descend onto the surface of the filter bag structure. High voltage is then connected to the cathode wire, which, in conjunction with the dust collecting plate, absorbs dust floating within the shell structure.

[0027] S3. When the position sensing module senses the moving position of the lifting assembly, the bag dust collector cleaning control system can synchronously control the lifting assembly to stop moving, and make the vibration assembly work, and cut off the power of the adsorption assembly, so as to shake off the dust attached to the dust collecting plate to the bottom of the shell structure for centralized processing, and then reset the lifting assembly.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. By setting up an adsorption component, a lifting component and a vibration component, after the pulse cleaning component removes the dust on the surface of the filter bag structure, the lifting component can drive the adsorption component to move from top to bottom, and use the principle of electrostatic dust removal to perform secondary adsorption treatment on the dust floating in the shell structure. When the adsorption component moves to the bottom of the shell structure, the vibration component can shake off the dust attached to the adsorption component, thereby avoiding the secondary attachment of dust to the filter bag structure. By setting up a pulse cleaning component and a bag dust collector cleaning control system, when the bag dust collector cleaning control system detects a decrease in the airflow velocity in the shell structure, it controls the pulse cleaning component to blow out compressed air to clean the filter bag structure, causing the filter bag structure to generate rapid expansion and impact vibration from the bag mouth to the bottom, causing the dust layer to deform and break, detach from the filter bag structure and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure;

DETAILED DESCRIPTION

[0042] The present invention will be further described in detail below with reference to the accompanying drawings.

[0043] Example 1:

[0044] refer to Figure 1-3 and Figure 9 A bag dust collector pulse jet cleaning device includes a bag dust collector main structure 1 and a bag dust collector cleaning control system 2. The bag dust collector main structure 1 includes a shell structure 101. The top of the shell structure 101 is bolted with a partition 102. The interior of the partition 102 is bolted with a number of evenly distributed filter bag structures 103. The top of the rear side of the shell structure 101 is connected to a fan structure 104. The top of the front side of the shell structure 101 is bolted with a pulse cleaning component 3. The rear side of the pulse cleaning component 3 extends into the interior of the shell structure 101. The pulse cleaning component 3 is used in conjunction with the filter bag structure 103. The top of the shell structure 101 is bolted with a lifting component 4. The bottom of the lifting component 4 extends to the inside of the shell structure 101, the bottom of the lifting component 4 is bolted with a vibration component 5, and the bottom of the vibration component 5 is bolted with an adsorption component 6. By setting a pulse cleaning component 3 and a bag dust collector cleaning control system 2, when the bag dust collector cleaning control system 2 detects that the air flow velocity in the shell structure 101 decreases, it controls the pulse cleaning component 3 to blow out compressed air to clean the filter bag structure 103, causing the filter bag structure 103 to produce rapid expansion and impact vibration from the bag mouth to the bottom, causing the dust layer to deform and break, detach from the filter bag structure 103 and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure 103.

[0045] like Figure 3 As shown, the pulse cleaning component 3 includes a compressed air tank 301, which is bolted to the top of the front side of the shell structure 101. The top of the compressed air tank 301 is connected to a plurality of electromagnetic pulse valves 302, and the top of the electromagnetic pulse valve 302 is connected to a flow-equalizing blowpipe 303. The bottom of the flow-equalizing blowpipe 303 is connected to a venturi 304. The venturi 304 is used in conjunction with the filter bag structure 103. By setting the pulse cleaning component 3, the bag dust collector cleaning control system 2 can detect When the flow rate of the air flow in the shell structure 101 decreases, the electromagnetic pulse valve 302 is controlled to operate, so that compressed air enters the uniform blowing pipe from the compressed air tank 301, and the compressed air is blown out through the venturi tube 304 to clean the filter bag structure 103, causing the filter bag structure 103 to produce rapid expansion and impact vibration from the bag opening to the bottom, causing the dust layer to deform and break, break away from the filter bag structure 103 and fall under the action of gravity, thereby achieving the effect of cleaning the filter bag structure 103.

[0046] like Figure 3 As shown, a fixing sleeve 9 is sleeved on the rear side of the surface of the uniform flow blowing pipe 303, a connecting rod 10 is bolted between the opposite sides of two adjacent fixing sleeves 9, a fixing rod 11 is bolted to the top of the connecting rod 10, and the top of the fixing rod 11 is bolted to the inner wall of the shell structure 101. By arranging the fixing sleeve 9, the connecting rod 10 and the fixing rod 11, the rear end of the uniform flow blowing pipe can be fixed to ensure its stability in use.

[0047] like Figure 9 As shown, the input end of the bag dust collector cleaning control system 2 is unidirectionally electrically connected to the power supply module 12, and the bag dust collector cleaning control system 2 includes a central control module 201, and the input end of the central control module 201 is unidirectionally electrically connected to the air flow velocity detection module 202 and the position sensing module 203, and the output end of the central control module 201 is unidirectionally electrically connected to the electromagnetic pulse valve 302, and the output end of the central control module 201 is unidirectionally electrically connected to the lifting component 4 and the vibration component 5, respectively. By setting the bag dust collector cleaning control system 2, the real-time air flow velocity in the shell structure 101 can be detected by the air flow velocity detection module 202. When the air flow rate drops to the set value, the central control module 201 controls the pulse cleaning component 3 to clean the filter bag structure 103. At the same time, it can also control the adsorption component 6 and the lifting component 4 to make the floating dust undergo secondary adsorption and centralized treatment. When the lifting component 4 drops to a certain distance, the position sensing module 203 can sense this position. At this time, the central control module 201 can synchronously control the lifting component 4 to stop moving, and make the vibration component 5 work, as well as the adsorption component 6 power off, to shake off the dust attached to the dust collecting plate 602 to the bottom of the shell structure 101 for centralized treatment.

[0048] Brief description of the use process: When the dust-laden gas enters the shell structure 101, the dust with a large specific gravity will directly fall to the bottom of the shell structure 101 under the action of gravity, while the dust with a small specific gravity will follow the gas through the filter bag structure 103, so that the purified gas flows from bottom to top and is discharged from the inside of the shell structure 101 through the fan structure 104. The dust is blocked by the filter bag structure 103, so that it adheres to the surface of the filter bag structure 103 and gradually forms a dust layer, which is detected by the air flow velocity detection module 202. The real-time air flow velocity in the shell structure 101, when the air flow velocity drops to the set value, the central control module 201 controls the electromagnetic pulse valve 302 to operate, so that the compressed air enters the uniform blowing pipe from the compressed air tank 301, and then the compressed air is blown out through the venturi tube 304 to clean the filter bag structure 103, causing the filter bag structure 103 to generate rapid expansion and impact vibration from the bag mouth to the bottom, causing the dust layer to deform and break, break away from the filter bag structure 103 and fall under the action of gravity.

The adsorption component 6, the lifting component 4 and the vibration component 5 can drive the adsorption component 6 to move from top to bottom through the lifting component 4 after the pulse cleaning component 3 removes the dust on the surface of the filter bag structure 103, and utilizes the principle of electrostatic dust removal to perform secondary adsorption treatment on the internal dust floating in the shell structure 101. When the adsorption component 6 moves to the bottom of the shell structure 101, the dust attached to the adsorption component 6 can be shaken off under the action of the vibration component 5, thereby avoiding the dust from being attached to the filter bag structure 103 for the second time.

[0052] like Figure 5As shown, the cathode wire 601 includes two metal rods 6011, which are bolted to the bottom of the vibration component 5. A connecting rod 6012 is welded between the opposite sides of the two metal rods 6011, and a number of discharge pinpoints 6013 are welded on the front and rear sides of the metal rods 6011.

The principle of electrostatic dust removal is used to perform secondary adsorption treatment on the dust floating in the shell structure 101.

[0053] like Figure 6 As shown, the dust collecting plate 602 includes an upper end cover 6021, which is bolted to the bottom of the vibration component 5.

The interior of the flat metal plate 6022 is provided with a plurality of dust collecting holes 6024. A dust collecting cavity is formed between the flat metal plate 6022 and the side opposite to the anode plate 6023. By setting the dust collecting plate 602 , it is composed of an upper end cover 6021, a flat metal plate 6022, an anode plate 6023 and a dust collecting hole 6024. When the anode plate 6023 is used in conjunction with the cathode line 601, based on the principle of electrostatic dust removal, the dust passes through the dust collecting hole 6024 and is adsorbed on the anode plate 6023. In addition, since a dust collecting cavity is formed between the opposite sides of the flat metal plate 6022 and the anode plate 6023, it can guide and limit the movement trajectory of the dust when shaking off the dust.

[0054] like Figure 7 As shown, the lifting assembly 4 includes a protective shell 401, which is bolted to the top of the shell structure 101. The rear side of the protective shell 401 is rotatably connected to a screw rod 402. The rear side of the top of the protective shell 401 is bolted to a lifting motor 403. The output end of the lifting motor 403 is bolted to the screw rod 402. The surface of the screw rod 402 is threadedly connected to a screw sleeve 404. The front side of the screw sleeve 404 is bolted to a moving rod 405. The bottom of the moving rod 405 is welded with a synchronization rod 406. The synchronization rod 406 is connected to the bottom of the moving rod 405. The bottom of 06 extends to the interior of the shell structure 101 and is bolted to the vibration component 5. By setting the lifting component 4, the screw 402 can be driven to rotate by the lifting motor 403. Under the thread cooperation of the screw sleeve 404 and the screw 402, the screw sleeve 404 drives the moving rod 405 to move, so that under the connection of the synchronization rod 406, the vibration component 5 and the adsorption component 6 are synchronously driven to move from top to bottom in the shell structure 101, thereby facilitating the adsorption of floating dust in the shell structure 101 by the adsorption component 6.

The movable sleeve 8 is bolted to the movable rod 405. The bottom of the screw 402 and the limiting rod 7 are respectively rotationally connected and bolted to the shell structure 101. By setting the limiting rod 7 and the movable sleeve 8, the movable sleeve 8 can be synchronously driven to move on the surface of the limiting rod 7 when the movable rod 405 moves, thereby ensuring the stability of the movable rod 405 during movement.

By setting up the vibration component 5, the dual-axis motor 503 drives the two eccentric blocks 504 to rotate, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block 504 is used to obtain an exciting force, thereby causing the lower connecting plate 502 to vibrate, so that the dust on the adsorption component 6 can be shaken off, and the setting of the rubber pad 505 and the spring 506 can prevent the vibration force from being transmitted to the upper structure, thereby ensuring the stability of the upper structure.

[0057] Brief description of the usage process: After the pulse cleaning component 3 completes the cleaning work of the filter bag structure 103, the lifting motor 403 can be controlled by the central control module 201 to drive the screw 402 to rotate, and the screw sleeve 404 and the screw 402 are threaded together, so that the screw sleeve 404 drives the moving rod 405 to move, thereby synchronously driving the vibration component 5 and the adsorption component 6 to move from top to bottom in the shell structure 101 under the connection of the synchronization rod 406, and then the cathode line 601 is controlled to pass current, so that the current is discharged through the discharge needle 6013, so that a non-uniform electric field is formed between the cathode line 601 and the anode plate 6023. The principle of electrostatic dust removal is used to make the dust pass through the dust collecting hole 6024 and be adsorbed on the anode plate 6023, and then the dust is adsorbed on the adsorption plate 6023. As the attachment component 6 continues to move, the position of the adsorption component 6 is sensed by the position sensing module 203, and a signal is sent to the central control module 201, so that it synchronously controls the lifting motor 403 to stop working and enables the dual-axis motor 503 to work. The dual-axis motor 503 drives the two eccentric blocks 504 to rotate, and utilizes the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block 504 to obtain the exciting force, thereby causing the lower connecting plate 502 to vibrate, shaking off the dust attached to the anode plate 6023, and causing it to fall to the bottom of the shell structure 101 in the cavity formed on the opposite side of the flat metal plate 6022 and the anode plate 6023, and then the central control module 201 controls the lifting motor 403 to reverse, so that the adsorption component 6 is reset.
